Application filed December 11, 1917. Serial 'No. 206,665.

To all whom it may concern:

Be it known that I, ANnRo NYLUND, a citizen of the United States, residing at Juneau, in the First Division of the Territory of Alaska, have invented certain new and useful Improvementsin Shingle-Cutting Machines, of which the following is a specification. I I

My invention relates to improvements in shingle-cutting machines.

One object of my invention is to provide a means of manufacturing shingles which shall eliminate waste of material.

Another object of my invention is to produce a uniform shingle that shall be thin at one end and thick at the other. J

Another object is to split or cut the shingle, in such manner that the fiber of the wood is not broken nor opened, thus rendering. the shingle more impervious to water and preserving the same.

A still further object is to give the shingle a crown so that when placed in position on the roof, or side of a building, the ends set closer to the roof, thus rendering it both windand water-proof.

In the accompanying drawings Figure 1 is a perspective view of the machine;

Fig. 2 is a top plan view of the bed-plate with the block-holder removed;

Fig. 3 is a longitudinal section on line 33 of Fig. 2;

Fig. 4 is a transverse section on line 4-4 of Fig. 2;

Fig. 5 is an enlarged top plan view of the shingle-block holder;

Fig. 6 is a transverse section on line 6 -6 of Fig. 5 as indicated by arrows;

Fig. 7 is a transverse section on line 7-7 of Fig. 5 disclosing only the means for gripping the ends of the block;

ig. 8 is a transverse section on line 8-8 of Fig. 5 as indicated by arrows, omitting the means for gripping the block from above;

Fig. 9 is a side elevation of the blockcarrier frame.

A, indicates the frame of the machine, consisting of upper and lower parallel beams 1, 1, supported at intervals by suitable vertical -supporting-posts 2, 2. Arranged longitudinally of the upper horizontal beams are parallel guiding-rails 3, 3, which are referably constructedof angleiron suitab y secured to the said horizontal beams. Slidably mounted within the main frame and upon the sliding-rails 3, 3, is a reciprocating carriage B. This carriage preferably consists of side-members 4, 4, and transverse beams 5, 5, said members 4, 4 provided on their outer edges with suitable guide-members 6, 6, which are adapted to rest upon the upper side of the slide rails 3, 3. Secured to the guide-members 6, 6, are additional angle-irons 7 7 which serve to confine the reciprocating bed to the guiderails 3, 3.

Arranged transversely of this frame, and centrally thereof is 'a double-edged knife 8, suitably secured to the side members of the reciprocating frame. Supported at either side of this knife are adjustable metal planer-beds 9, 9, the outer ends of which are adjustably supported by laterally-extending lugs 10, which are received within suitable slots 11, 11, arranged in the side of the reciprocating frame. The forward ends of the planer-beds are supported by vertically adjustable screws 12, 12, supported by lugs from the sides of the main frame.

Arranged transversely beneath the double-edged knife 8 are compensating lips 14, 14, secured by suitable hinges 14' to the outer ends of the adjustable planer beds 9, 9, as disclosed in Figs. 2 and 3. The numeral 15 indicates compensating springs which are secured as at 16 to the planer-bed, the outer free ends of which are adapted to pass beneath the transverse compensating lips. The tension of these compensating springs is regulated by suitable mechanism which preferably consists of a transverse bar 17 secured to the under side of the planer-bed, which is provided with adjustable screws 18, provided at their outer end with spiral springs 19, which serve to pressagainst the tension springs 15, upon the adjustment of the screws 18. These planer-beds are capable of horizontal adjustment with respect to the double-edged knife 8, being provided centrally thereof at the outer end with threaded lugs 20, which are adapted to receive a horizontally-arranged rotatable worm-screw 21, provided at its outer end with an adjusting wheel 22. Numeral 23 indicates transverse rods extending laterally of the reciprocating frame at either end thereof, and secured thereto b suitable supporting plates 24. Connecte to these rods are any suitable reci rocating mechanisms (not shown).

cans are provided directly above the re' ciprocating frame Bfor holding in proper relation thereto the shingle-block, from a frame are suitable supporting members 25,

25. Arranged between these supporting members are supporting-plates 26, which are arranged longitudinally with relation to the main frame. These plates are preferably arranged in pairs, and support at one end a' transverse cylindrical gripping-bar '27,-

flattened on the inner side thereof. Directly opposite this bar is a horizontally adjustable bar 28, provided with a plurality of grippingteeth 29. These teeth in this instance comprise pointed tap-screws 30. The outer ends of the gripping-bar 27 are squared I to receive links 31, 31, to the outer free ends of which are fastened connecting-links 32,

32, which extend between the pairs of supporting-plates 26, and are connected to the outer ends of the horizontal adjustable bar 28. An adjusting lever 33, secured to the gripping-bar 27, serves, when actuated, to draw the horizontal adjustable bar 28 toward the gripping bar 27, and secure the shingle block 34 therebetween.

As a means for properly positioning the shingle block 34 from above, and preventing possible vertical movement of the block, while being moved toward the knife 8 I preferably arrange a pivoted frame 35 above the shingle-block holders, the pivoted end of which is supported by rod 36 supported at its outer ends by suitable uprights 36' extending vertically from the supporting-members 25. This frame'is provided at its outer free end with an actuating-handle 37. Supported by this frame is a set of rollers 38, provided with gripping-dogs 39, which are adapted to grip the shingle-block upon its upper side. To actuate these dogs, I mount on the outer free ends of the rollers 38 suitable spur-gears 40, which are adapted to mesh, and arrange on the end of one of said rollers an actuating lever 41, which, as it will be seen, when actuated will cause the gripping dogs to contact with the upper surface of the shingle-block.

These rollers are preferably supported at either end by suitable hangers 42 suspended from the pivoted frame 35. These hangersare preferably pivotedas at 43 to the main frame 35, in order that the gripping-dogs 39 may properly adjust themselves to the shingle-block.

When first inserting the shingle-block into the frame, it is desirable to support the frame'35 in an uppermost position. For this purpose, I arrange transversely of the supporting-members 25, 25, a removable plate which is received upon the supportingmembers 25, 25, which when not in use is in aposition as shown in Fig.5. When it is desirable to insert a block in the machine, the frame 35 is moved vertically upon its pivot, and the plate 44 is drawn horizontally beneath the gripping dogs 39, serving to hold them up out of the way while the shingle-block is being placed upon the bedplate 9, after which the plate 44 is pushed back, permitting the frame and grippingdogs 39 to be lowered into engagement with the upper surface of the shingle-block.

As will be seen, the bed-plates 9, 9, are adjustable at a slight'an le with res ect to the. cutting knife 8, whic has the e ect of giving the shingle block a slight tilt when inserted in the machine, the block being held down upon the bed-plate by the dogs 39,

after whichthe lever 37 is actuated, and the block gripped in its tilted'position.

frame B, the knife 8 travels in ahorizontal position, and slices off a shingle, which, owing to the tilted position of the block, roduces one which is thinner at one end. he carriage travels the extreme length of the machine, whereupon the lever 33 is actuated, and the shingle-block is released when the dogs 39 are actuated to release the block, permitting it to drop down upon the bedplate 9 at the opposite end of the machine, and again assumes a tilted position opposite to that of its former position, after which the dogs 39 again engage the block, which is again gripped by the actuation of the lever 37, whereupon the reciprocating frame B is shifted to the opposite end of the frame, and another shingle is sliced from the shingleblock, which also is thinner at one 'end. This arrangement of alternately tiltin the block at each operation in opposite irection serves to equalize the unevenness produced by slicing oil a shingle of uneven thickness at its ends, and results in a great savingof material in producing this form of shingle.

As will be seen, I have constructed a device which is very economical in theproduction of tapered shingles, and one which is very simple in construction and effective in results.
